A Correct answer
Explanation

In partnership problems, profit is distributed in ratio of investment × time. Ram: 10000×12 = 120000. Raja: 12000×12 = 144000. Ajay: 18000×9 = 162000 (joined after 3 months). Total ratio units = 426000. Ram's share = 21300 × (120000/426000) ≈ 6000. Ajay's share = 21300 × (162000/426000) ≈ 8100. Difference = 2100.
